Set oscilloscope trigger back to auto

Hi,

 

I am running Labview 8.2.1 to control Wavesurfer 64xs oscilloscope viaTCP/IP. The drivers are downloaded from NI

http://sine.ni.com/apps/utf8/niid_web_display.model_page?p_model_id=14665.

 

 

The oscilloscope acquires signals in bursts, and I need to use average (~10) to reduce the noise. The signals are controlled to change immediately after the previous data being read and stored. But the program "Read Signle Waveform.vi" can only wait 1 single trigger and stop, which I found is beacuse the subprogram "Initiate.vi" will write the buffer code "*CLS;ARM;" to the oscilloscope. So I am not be able to do averaging on the oscilloscope now.

 

I am wondering how can I set it back to auto trigger aftering reading the waveform, or alternative methods to realize averaging.

 

Thanks so much...
